Seems the power cut on Friday (only 4 mins or so it seems) shut off lots in the shack and workshop. I was wondering why stuff was in a wierd state when realised that the shack webserver had restarted.
Half is on UPS other half isn't.
Time to buy some new UPS I think, don't really want to bodge it by adding a car battery to extend runtime as the UPS are line interactive. 500VA units look cheap as chips these days.

Car batteries are built to deliver high current for a brief period, then be recharged. Running them down with a UPS is a good way to abuse them. If you are getting an extra battery, best to get one built for deep cycle use.
ReplyDeleteA caution, some have reported that cheap UPS units rely on the battery running down before the inverter overheats - extra battery would not be good there unless you were running at only a fraction of the output capacity.
